YANZEO 10pcs 5MM NFC RFID 213 Chip Inside Mini Bluetooth Pairing RFID NFC Tag Programmable NFC Card Control Management Works to Android NFC Smartphones Devices

This chip works great, the supplier sent out immediately and it arrived fast. The chip does what it is suppose to do. I love the chip, I am happy with the supplier. The chip works if it is just the chip and just the speed that I received them then I would give 5 stars and a personal testimony. However the price is hi for such a small chip that is produced by the millions. The price is why I cannot give five stars. There are other places you can get cheaper and not pay shipping and the tax is not so high. However the company is great the chip is great and I will recommend but the price is high and for the projects I do and am attempting the price is hindering me and setting me back in order to complete.My only negative is the price. Everything else is great including the company.

I’ve tried several approaches but the tag does not work. It does not specify what it works with, but it is not IOS/iPhone.It’s awfully expensive for something with no instructions or information.Save yourself the time, money, and frustration and buy something that works.Side note: for the people that say it’s great, maybe providing some information on what device you’re using or where you found instructions.

Using iPhone 16 Pro and the NXP Read/Write apps these NFC stickers have to be touching the phone case to be sensed. The working distance This would render these NFC stickers useless unless you can get the phone on top of and touching them. You may even have to take your phone out of its case depending on how thick the case is. Consider buying a NFC sticker that has an antenna with larger cross-sectional area

This rfid tag works great however it breaks easily if around water too frequently or exposed to flexing.

These are indeed tiny. Don't drop them anywhere that can hide a small square, you won't find them. They work with my Samsung phone. I haven't tried to write protect one, but I have written (and erased) one of these several times.

These are small and discreet but work as well as a larger discreet does.

The size is exactly what I needed but my phone couldn't pick up the signal to even write on them, it doesn't come with instructions or even a program to work with it I've tried 10 different apps and none of them work

The antenna is really small so the sensitivity is poor. I used my cellphone to write and read to it but I had to remove my case and put the tag up against the back of my phone to get it to read or write. It maybe better if I had a dedicated RFID tool.
